The datatable draws from a database list. this.cboList.DataSource = pullData(); this.cboList.DisplayMember = "fieldA"; Once the DataSource is set I am not able to insert a default row (ie *) as the first item in the combobox. I tried this: this.cboLis...

I'm going through a final check of some of my code, and made a few name changes here and there to keep all of the naming conventions consistent. Now I'm running my code, and when I try to close a form using WinForm.Close();, it doesn't close anymore. I changed all of the names corresponding to the WinForm correctly, so I'm confused a...

One of our company's Windows Forms application had a strange problem for several month. The app worked very reliable for most of our customers but on some PC's (mostly with a wireless lan connection) the app sometimes just didn't respond anymore.
